asus realtek hd audio manager rear speakers not working

I ended having to plug headphones into the headphone jack in front of computer, and the speakers into the back to the light green lower center jack (front speaker out). I wanted to be able to switch between using speakers or headphones using only realtek audio vs physically switching ports/jacks. I have asus cm1855 w/ windows 10 & realtek audio manager.

I finally figured it out after 2 hours, same issue as nitsua101. Really? But Asus's website says that it supports jack-retasking and I have seen it been done on other fourms with an Asus Realtek manager. If you want to task between the two, I recommend either a USB headset, or using the Front Panel to override your speakers when you want just headphones so you don't have to climb behind your case. The only workaround I can think of that would work is to have both plugged in and change your Speakers from Stereo or 2.1 to Quadraphonic (4 speakers) but then you might lack certain sound in your headphones, and I'm assuming you're trying to isolate certain sound, i.e.

You either have your speakers or your headphones. Those inputs are driven a certain way on the circuit board, you can't just tell the Line In to pretend to be a second Line out, or the Side speaker or Rear Speaker input to be a second stereo out. It can't retask jacks because that's just how they work, nothing wrong with your drivers.
